So you were in a very small pond, which is a huge issue in combat sports training. I taught Judo in a very rural, isolated area of Canada, so I am very familiar with the problem.
And sparring from the very beginning is not necesssarily the best idea in the world, despite what some folks here may write or think. Sparring covers a lot of ground. It’s the same problem in Judo.
Early full on sparring (randori in Judo), tends to sort folks out into the more aggressive, and/or athletic or both (they are interacting variable), and that can tend to do two things: Encourage bad habit among the more athletic/aggressive, and discourage the less so from participating.
I get so sick of watching noobs (and not so noobs) posting video of themselves in judo comps, and watching them make so many fundamental mistakes and think they are doing well because they throw some guy and win a match or three, or worse, win a medal in a noob level division via aggression/physical domination.
Don’t get me wrong, aggression and phyusical domination in a combat sport is part of the deal, however, at noob level, it can mess people up badly if not managed carefully.
